Our factory independently develops and produces sound-absorbing sponge, sound-absorbing sponge, and sound-insulating sponge. These are produced by foam production using polyurethane materials. They have good sound absorption, noise reduction, and shock absorption effects. The pyramidal material is filled with small pores, and the semi-open structure can absorb a large amount of sound energy, attenuating sound waves, making it a high-performance product for sound absorption, noise reduction, and shock absorption materials. It has sound-absorbing ability and fire resistance, which can be applied to: vehicle construction, factory building sound absorption and building sound insulation engineering, product packaging and padding, power generation set sound absorption, air conditioning, acoustic laboratories, music recording studios, sound equipment, test sound rooms, surveying rooms, KTV rooms, star-rated hotels and other industries and venues.
